Muldrotha, the Gravetide + Displacer Kitten + Extruder + Armor Wars

Muldrotha, the Gravetide

Displacer Kitten

Extruder

Armor Wars

How it works

1. Cast the artifact from your graveyard by paying 0.
2. Displacer Kitten triggers, blinking Muldrotha.
3. Activate Extruder by sacrificing the artifact.
4. Repeat.

This intricate loop turns your graveyard into an endless workshop by leveraging Muldrotha, the Gravetide to repeatedly cast a zero-mana artifact from the graveyard. Every time you cast that noncreature spell, Displacer Kitten triggers to blink Muldrotha, resetting her permission so you can cast the artifact again. Meanwhile, Extruder provides the sacrifice outlet needed to put the artifact back into the graveyard while growing your creatures with endless +1/+1 counters. Even though Armor Wars sits on the board contributing its own saga chapters, this core engine spins infinitely to flood the battlefield and pile up sacrifice triggers.
